Maybe I should've been a bit more specific.. I was only going with the flow of everyone else in this thread that they were only posting one-piece-per-slot set-ups. As for gear-swaps, I agree in using them but only if one can afford the equipment to do so. I myself am barely able to afford new equipment because I've not the time to make much gil - therefore, I take what I can get and work with it. If I can afford a piece at the time and it's something that'll help in the long run, I'll buy it to use for swaps - otherwise, if it isn't up to my standards, I don't see a point (i.e. buying a piece that gives a mere +1 more STR with less overall bonuses, that costs hundreds of thousands of gil more.. as compared to the piece I have at the time that also gives more overall).
In regards to having a weak job, DRG is not a weak job but merely one that calls for a bit more strategic way of using WSs and the job abilities from both main and sub. That's how I look at every job - none are truly stronger than the other, just each has their own way of being done. Every person finds their own way to make them good at the job; just some people do it differently and are very good in how they perform. As for a player being weak, that's only if said players are closed-minded - such as those who do not wish to give people a chance by inviting them into a party, but rather just shrug them off as though they aren't human themselves.
People choose their jobs typically because they enjoy that job; not necessarily to be the strongest or best. Why else would some BSTs choose to take their jobs all the way and even create a linkshell comprised almost entirely of such? Or why high-level DRGs continue to adjust themselves to various situations and the sub-job they choose? DRG is a flexible job that has many possibilities for what it can do; then again, almost any job is like that. It just depends on the person's mind set and what goal they have set for themselves. Why else do you think there are PUPs out there who've already made it to 75 and love the job? Or SMNs who refuse to main heal and get invited into parties as a DD and do well at it? It's because they've honed their skills to achieve their goals and were given the chance to work with others while doing so. Unless you are looking to fill a specific position (i.e. needing a RDM for Dispel against certain monsters, or a WHM to main heal), give the jobs a chance and don't push them away. Never know what you mind end up with - yes, there will be some bad ones, but there's always that possibility of getting those good ones who'll really shine.
